Frightfully good fun adds to the excitement of the Disneyland Resort Diamond Celebration this autumn, as the Halloween season arrives at the resort Sept. 11 and runs through Nov. 1.

The annual, family-friendly Halloween experience includes spooky transformations of Haunted Mansion and Space Mountain, plus special décor, themed foods and merchandise. In addition, the separate-ticket Mickey’s Halloween Party offers guests an opportunity to visit in costume and trick-or-treat throughout Disneyland Park, on 17 selected nights.

Haunted Mansion Holiday in New Orleans Square has become a thrilling Disneyland Halloween tradition, with Jack Skellington from the Walt Disney Pictures classic “Tim Burton’s The Nightmare Before Christmas” moving into the Mansion to spark a collision between Halloween and Christmas. As in past years, some eerie new touches have been added to the Haunted Mansion Holiday experience. The Hatbox Ghost, who recently rejoined the Mansion’s happy haunts, is staying to celebrate Halloween and Christmas with Jack Skellington and his friends.

Inside the Mansion, the 15th annual Haunted Mansion Holiday gingerbread house resembles a leaning and careening “house of cards” this year. A corps of zombie gingerbread men in orange-frosting safety vests stands beneath the towering confection to supervise construction while a team of “helicopter bats” hover above the teetering tower. The “helicopter bats” are lowering spiders that will add the final gingerbread cards to the tower from their sticky, suspended webs.

Another Halloween favorite is Space Mountain Ghost Galaxy, a Halloween-themed reimagining of the popular thrill ride in Tomorrowland. Guests on board the speeding Space Mountain vehicles are thrust into a ghostly galaxy where they are bombarded with eerie screams, sound effects and music. Spine-chilling spirits pop out of the darkness, appearing to reach out and menace space travelers.

In Frontierland, guests will enjoy the observation of the traditional Mexican “Dia de los Muertos” celebration with a skeleton display near Rancho del Zocalo restaurant.

The popular separate-ticket, after-hours Mickey’s Halloween Party returns this year, expanding to 17 nights beginning Friday, Sept. 25, with an array of special entertainment. For the first time, the “Paint the Night” parade, which made its debut in May for the Diamond Celebration, will be presented during this special event. In addition, the “Halloween Screams” fireworks spectacular and the “Monsters U Dance Party” at Tomorrowland Terrace are exclusive to Mickey’s Halloween Party.

Tickets purchased in advance are available at a discount on select nights. Tickets purchased on the day of the event are $77 each. All tickets to Mickey’s Halloween Party on Thursday, Oct. 29, are $84 each. Mickey’s Halloween Party is a non-smoking event. Smoking will be permitted only in the Esplanade outside the Disneyland main entrance.

Throughout Halloween Time at Disneyland Resort, guests also will be able to enjoy the 60th Anniversary Diamond Celebration with its sparkling enhancements on Sleeping Beauty Castle in Disneyland and the Carthay Circle Theatre in Disney California Adventure, plus a dazzling array of after-dark shows. In Disneyland, the “Paint the Night” parade creates a river of color down Main Street, U.S.A., with spectacular special effects, sensational floats, energetic performances and unforgettable music. The “Disneyland Forever” fireworks show in Disneyland lights up the resort with dynamic pyrotechnics and magical projections that surround the audience.

In Disney California Adventure, the Diamond Celebration comes alive in “World of Color – Celebrate! The Wonderful World of Walt Disney.” The magical water show – filled with film, lasers, music and special effects – pays tribute to Walt Disney with colorful fun and surprises, honoring the man whose fertile imagination led to the creation of Disneyland and so many beloved characters.

Halloween thrill-seekers will enjoy visiting Disney California Adventure to sample year-round excitement on California Screamin’ roller coaster, Radiator Springs Racers, Soarin’ Over California and Grizzly River Run. Guests may also mingle with the ghosts in The Twilight Zone™ Tower of Terror, or dance the night away in the after-dark Diamond Mad T Party.
